Fiber-Reinforced Polymer (FRP) composites, used in various applications and environments, are often chosen over conventional materials for their durability. In cold temperatures, especially, designers expect longer lifetimes and lower maintenance for FRP composites as compared to conventional materials. However, the performance of FRP composites can be adversely affected by environment. For applications in civil infrastructure, for example, stiffness and strength degradation can be aggravated by deposits from road-salts in addition to moisture induced swelling and drying from freeze-thaw. The implications of such effects for long-term performance and design must be well understood for successful implementation of FRP composites at very cold temperatures.The proposed objectives are:1. Define the state of the art with regards to behavior and prediction of performance of FRP composites at very cold temperatures2. Identify gaps in the knowledge base regarding behavior and prediction3. Stimulate ideas for research and collaboration based on the existing knowledge base of FRP composites and other materials at very cold temperatures4. Draft an integrated research plan for performance and design of FRP composites at very cold temperaturesThe intellectual merit of the proposed workshop lies in the bringing together of researchers with diverse expertise and the integration of knowledge in different topic areas to advance the state of the art. The study of the performance and design of FRP composites at very cold temperatures spans materials engineering, manufacturing, predictive modeling, and reliability-based measures for incorporation into design procedures. The PI has a good plan to identify the right people.In the area of broader impacts, the workshop will benefit society through improved application of FRP composites at cold temperatures, where the benefits of FRP over conventional materials can be fully realized.

纤维增强聚合物（FRP）复合材料，用于各种应用和环境中，通常选择超过传统材料的耐用性。特别是在寒冷的温度下，与传统材料相比，设计人员希望FRP复合材料具有更长的使用寿命和更低的维护费用。然而，FRP复合材料的性能会受到环境的不利影响。例如，对于民用基础设施中的应用，除了水分引起的膨胀和冻融引起的干燥之外，来自道路盐的沉积物也会加剧刚度和强度退化。这些影响对长期性能和设计的影响必须被很好地理解，以便在非常寒冷的温度下成功地实施FRP复合材料。定义FRP复合材料在极冷温度下的行为和性能预测方面的最新技术水平2。确定知识库中关于行为和预测的差距3。基于现有的FRP复合材料和其他材料在极冷温度下的知识库，激发研究和合作的想法4。起草一份综合研究计划，用于在非常寒冷的温度下FRP复合材料的性能和设计拟议研讨会的智力价值在于将具有不同专业知识的研究人员聚集在一起，并整合不同主题领域的知识，以推进最先进的技术水平。在非常寒冷的温度下FRP复合材料的性能和设计的研究跨越了材料工程，制造，预测建模，和可靠性为基础的措施纳入设计程序。PI有一个很好的计划来确定合适的人。在更广泛的影响领域，研讨会将通过改善FRP复合材料在低温下的应用来造福社会，在那里FRP相对于传统材料的好处可以充分实现。
